Keep active pull request sandboxes from timing out
Protect a useful review environment when the pull request keeps evolving.
Trigger
Pull Request Updated
Triggers when an existing pull request is updated in a GitHub repository. Updates include title edits, description changes, label changes, assignee changes, reviewer requests, draft status changes, base branch changes, being closed, merged, or reopened. Only pre-existing PRs that receive an update will fire the trigger; newly created PRs are excluded. Supports optional filters: state, base branch, head branch, author, label, and draft status.
Action
Set Sandbox Timeout
Tool to set the timeout for an E2B sandbox. Use when you need to extend or reduce the sandbox lifetime. The timeout is measured from the current time, and calling this multiple times overwrites the previous TTL.
Why this helps
Long-running reviews lose momentum when their workspace expires before the next decision.
- Keep active reviews available
- Reduce repeated environment setup
Setup
Build it in a few focused steps.
- 1Connect GitHub and E2B to Notis once.
- 2Create a new portal automation.
- 3Tell Notis to extend the matching E2B sandbox timeout when an existing pull request is updated, select Pull Request Updated, and choose a channel.
- 4Update a test pull request to verify the timeout change.
Questions about this workflow
Can the timeout be adjusted later?
Yes. Edit the plain-language automation prompt whenever the team needs a different lifetime.

Supported Triggers and Actions
Notis builds workflows that link GitHub to E2b. A trigger fires from one place; an action lands in another.
GitHub triggers
E2b actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Connect to Sandbox
Tool to connect to an existing E2B sandbox and retrieve its details. Use when you need to reconnect to a sandbox from different environments or resume a paused sandbox. The TTL is extended upon connection.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Create Template
Tool to create a new E2B template with specified configuration. Use when you need to define a new sandbox template that can be used to spawn sandbox environments.
New Workflow Artifact Created
Triggers when a new workflow artifact is created in a GitHub repository. Monitors for newly created GitHub Actions workflow artifacts. Optionally filters by artifact name to restrict monitoring to specific artifacts.
Create Webhook
Tool to register a new webhook to receive sandbox lifecycle events for the team. Use when you need to set up notifications for sandbox lifecycle events such as creation, updates, or termination.
Branch Changed
Triggers when a GitHub branch changes. Monitors a specific branch for: - New commits pushed (head commit SHA changes) - Protection status toggled (branch becomes protected or unprotected) - Protection settings changed, including: required status checks and their enforcement level, admin enforcement, required pull request reviews (dismiss stale reviews, code owner reviews, approving review count, last push approval), required linear history, force push allowance, deletion allowance, conversation resolution, branch locking, and fork syncing.
Delete Sandbox
Tool to terminate and permanently delete a running E2B sandbox instance. Use when you need to kill a sandbox that is no longer needed. Once terminated, the sandbox cannot be resumed.
New Branch Created
Triggers when a new branch is created in a GitHub repository. Detects newly created branches. Deleted branches do not fire events.
Delete Webhook
Tool to unregister a webhook and stop receiving lifecycle events. Use when you need to remove a webhook that is no longer needed or to clean up webhook registrations.
Check Run Status / Conclusion Changed
Triggers when a specific GitHub check run changes its status or conclusion. Monitors a single check run for changes to: status (queued, in_progress, completed, etc.), conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required), started_at, and completed_at.
Check API Health
Tool to check the health status of the E2B API. Use when you need to verify that the API service is operational and accessible.
Check Suite Status / Conclusion Changed
Triggers when a GitHub check suite changes its status or conclusion for a given ref. Monitors all check suites associated with a git reference (branch, tag, or commit SHA) for changes to status (queued, in_progress, completed, etc.) and conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required, startup_failure, stale). Optionally filters by GitHub App ID.
Get Sandbox
Tool to retrieve detailed information about a specific sandbox by its ID. Use when you need to check sandbox status, metadata, or configuration details.
New Code Scanning Alert Created
Triggers when a new code scanning alert is created in a repository. Fires an event for each newly created code scanning alert detected in the configured repository. Alerts can be filtered by Git reference, scanning tool, state, and severity. The payload includes the alert number, rule details, tool information, state, severity, and the location of the most recent instance.
Get Sandbox Logs
Tool to retrieve logs from a specific E2B sandbox instance. Use when you need to debug or monitor sandbox execution by viewing its console output and system logs.
